Answer:

length: 38 feet

width: 10 feet

area: 380 ft²

Step-by-step explanation:

The scale between the drawing and the actual studio is 2 in : 5 ft. If we divide both sides by 2, we find that the scale is 1 in : 2.5 feet.

For the first number, 15.2 inches, if we multiply it by 2.5 and change the label to "feet", we can find the real length.

15.2 * 2.5 = 38.

The length is 38 feet.

For the width, do the same thing.

4 * 2.5 = 10

The width is 10 feet.

Area is length times width. So if we plug in the numbers we just found:

38 * 10 = 380.

The area is 380 ft²

Answer:

[tex]A=(x^2+16+8x)\ \text{inches}^2[/tex]

Step-by-step explanation:

Given that,

The side length of a square, l = (x+4) inches

We need to find an expression to represent the area of the square.

The area of a square is given by :

[tex]A=\text{side}^2[/tex]

So,

[tex]A=(x+4)^2\\\\A=(x^2+16+8x)\ \text{inches}^2[/tex]

So, the area of the square is [tex](x^2+16+8x)\ \text{inches}^2[/tex].

Answer:

DF ≅ AC

Step-by-step explanation:

To prove that the triangles are congruent by AAS, we need a side from each triangle to be congruent to the other, correspondingly. So, if AC ≅ DF, we could prove the triangle's congruency by AAS. In the answer choices, the only answer that works is DF ≅ AC.

Answer:

8 batches

Step-by-step explanation:

A recipe for cookies calls for 2/3 of a cup of sugar. Elena used 5 1/3 cups of sugar to make multiple batches of cookies. How many batches did she make?

From the above question, 1 recipe = 1 batch of cookies

Hence:

2/3 cup of sugar = 1 batch of cookies

5 1/3 cups of sugar = x batches of cookies

Cross Multiply

2/3 cup × x batches = 5 1/3 cup × 1 batch

x batches = 5 1/3 cup × 1 batch/2/3 cup

x batches = 16/3 ÷ 2/3

x batches = 16/3 × 3/2

= 8 batches

Therefore she made 8 batches

The monthly rent during the 8th year of living in the apartment will be $2160.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

You rent an apartment that costs $800 per month during the first year, but the rent is set to go up by $170 per year.

Then the monthly rent during the 8th year of living in the apartment will be

Let y be the monthly rent and x be the number of years.

Then we have

y = 170x + 800

The rent after 8 years, then the rent will be

y = 170 × 8 + 800

y = 1360 + 800

y = $ 2160

Thus. the monthly rent during the 8th year of living in the apartment will be $ 2160.

Explanation:

Think of 6 + y - 3 as 6 + 1y - 3

y and 1y are the same thing because 1 times any number is that same number.

The coefficient is the number to the left of the variable, so the coefficient is 1.

Answer:

6 race cars

Step-by-step explanation:

In this scenario, there would be a total of 6 race cars on the scale. Since each racecar weighs 1/4 pound then 4 racecars would equal 1. This leaves us with 1/2 or 0.5 pounds left. This would be 2 race cars since 2/4 is equal to 0.5 pounds. Therefore, if we add these two amounts up it would be a total of 6 racecars (4+2) which would total 1 1/2 pounds.

Answer:

a. m<DAB = 36°

b. m<B = 54°

c. m<C = 74°

Step-by-step explanation:

a. m<DAB = m<CAB + m<CAD

m<DAB = 20° + 16° (substitution)

m<DAB = 36°

b. m<B = 180° - (90° + m<DAB)

m<B = 180° - (90° + 36°) (substitution)

m<B = 54°

c. m<C = 180° - (90° + m<CAD)

m<C = 180° - (90° + 16°) (substitution)

m<C = 74°

Answer:

  x

Step-by-step explanation:

There is already an expression given for x, so that is the easiest variable to substitute for.

Substituting for x using the second equation, you have ...

  -3(-2y+14) +y = -14

  6y -42 +y = -14

  7y = 28

  y = 4

  x = -2(4) +14 = 6

The solution is (x, y) = (6, 4).

_____

Substitution for x is the easiest.

__

The first equation could be rearranged to give an expression for y:

  y = 3x -14

Then that can be used to substitute for y in the second equation. My lazy brain judges that to be more work.

7x² - 26x + 9

Step-by-step explanation:

(g(x)²) = (3x - 2) (3x - 2)

(g(x)²) = 9x² - 6x - 6x + 4

(g(x)²) = 9x² - 12x + 4

(9x² - 12x + 4) - (2x² + 14x - 5) = 7x² - 26x + 9
